Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to implement a full-screen display on mobile terminals with integrated cameras, where the camera's presence limits the screen design, making it difficult to achieve a seamless display due to space constraints.
Innovation Solution
A display device with a first display area and a second display area, where the second area has lower resolution pixels and light-transmitting areas, allowing the camera module to be placed, ensuring sufficient light transmittance and image quality through specific pixel arrangements and light-emitting element configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a camera module is integrated into the display screen to achieve full-screen display, then the screen size and display area are improved, but the image quality in the imaging area deteriorates due to low-resolution pixels and light-transmitting areas
Solution Approach 1:
The patent applies local quality by creating different pixel configurations in different regions of the display. The imaging area (where the camera is located) has light-transmitting areas and lower-resolution pixels, while non-imaging areas have full-resolution pixels. This allows each region to have the specific properties needed for its function: light transmission for camera operation and high resolution for display quality.
Solution Approach 2:
The display is segmented into multiple pixel groups with different characteristics. Specifically, pixel groups in the imaging area have different compositions (with fewer or no light-emitting elements) compared to pixel groups in non-imaging areas. This segmentation allows the display to simultaneously support both camera functionality and high-quality imaging in different regions.
2Reliability
If light-transmitting areas are created in the display panel for camera light access, then camera performance is improved, but the uniformity of image quality across the display deteriorates
Solution Approach 1:
The patent changes the parameters of pixel groups based on their location. Pixel groups in the imaging area have different numbers of light-emitting elements, different arrangements of sub-pixels, and different light transmission characteristics compared to pixel groups in non-imaging areas. These parameter changes enable the display to optimize both camera performance and overall image quality uniformity.
Solution Approach 2:
The display employs composite pixel structures where pixel groups in the imaging area combine light-transmitting areas with reduced or modified light-emitting elements, while pixel groups in non-imaging areas maintain full light-emitting element configurations. This composite approach allows the system to achieve both camera functionality and display uniformity.
3Area of stationary object
If low-resolution pixels are disposed in the imaging area for camera integration, then full-screen display is achieved, but the picture quality in the imaging area deteriorates
Solution Approach 1:
The patent addresses the resolution issue by transitioning to a three-dimensional spatial arrangement. Instead of simply reducing pixel density in the imaging area, the patent uses multiple pixel groups with different compositions and arrangements (including different numbers of sub-pixels per pixel group) to maintain adequate resolution while allowing light transmission for camera operation.

AI summary
A display device includes a first display area including a plurality of first pixel groups, and a second display area including a plurality of second pixel groups and a plurality of light-transmitting areas. Each of the plurality of second pixel groups includes a plurality of sub-pixels, and in any one sub-pixel of the plurality of sub-pixels, a light-emitting element is disposed in a light-transmitting area from the plurality of light-transmitting areas that corresponds to the any one sub-pixel.
